Does anyone know of any xUnit testing frameworks for the Mac OS, more specifically for the iPhone OS? I've seen a couple online, google-toolbox-for-mac & objcUnit, but they don't seem to have had any development on them for a long time. Are there any Objective-C developers out there that perform unit testing and if you do what tools do...

EDIT: I originally asked this question in regards to general view resizing, but I realize now that it's something much more specific to tableViews. Say that a tableView originally has a frame of (0 0, 320 460), i.e., it fills an entire iPhone screen. In order to resize the tableView's height and animate the resize, I map the following ...
